Remove doctype for user permissions

hello , I want to restrict a user from using certain doctypes .
for example the role stock manager contains many permissions . I want to remove one for only one user . according to my researches I need to duplicate that roles and copy all the permissions except that one I want to remove . that is gonna take too much time . is there a way to just restrict a doctype for certain users . it’s like permitted documents for user but the opposite

you do not need to maintain new role permission via permission manager one by one. instead please try to import permission details for DocType Doc Perm via data import.
